The Silverton Tramway Y class was a class of 2-6-0 and 2-6-2 T steam locomotives of the Silverton Tramway Company, operating between Broken Hill, New South Wales, and the border of South Australia.
Between 1888 and 1907 the Silverton Tramway Company took delivery of eighteen 2-6-0 and two 2-6-2 T locomotives from Beyer, Peacock & Co, Manchester, and two built by James Martin & Co purchased second-hand from the Tarrawingee Tramway. [1] [2] [3]
The company notionally had 21 Y class locomotives, although three were never operated and only a maximum of 17 were owned at any one time. Their road numbers were recycled. [1] [2] [3]
In 1887, having commenced operations with hired South Australian Railways Y class locomotives, the company ordered four locomotives of the same design from Beyer, Peacock. They were assembled in Gawler, South Australia by James Martin's Phoenix Foundry. Since the company had an option to sell to the South Australian Railways any that it deemed surplus, two of the locomotives ("1st Y3" and "1st Y4") passed without use. Of the other two, which were 2-6-2T (side tank) locomotives but otherwise the same as the 2-6-0 locomotives, one was sold within a few months; the other was given away as compensation for a collision 11 years later. [4]
Westinghouse air brakes were fitted to Y13, Y15 and Y16 from new and Y1 and Y11 were retrofitted. Y1, Y6, Y8 and Y11 to Y17, which originally had a boiler pressure of 145 pounds per square inch (1000 kilopascals; 10.2 kilograms-force per square centimetre), were rebuilt with 180 pounds per square inch (1200 kilopascals; 13 kilograms-force per square centimetre) boilers and lead adhesion slabs were added to the running boards. Three were superheated between 1924 and 1926. [1]
The locomotives were superseded on main line duties by the A class from 1912 onwards, but many were retained for shunting and secondary duties around the Broken Hill yards and mine sidings. The last was withdrawn in 1961. [1] [3]
The locomotives' disposition as of 2015 [update] is shown in the table.

A Garratt locomotive is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage.
Beyer, Peacock and Company was an English general engineering company and railway locomotive manufacturer with a factory in Openshaw, Manchester. Charles Beyer, Richard Peacock and Henry Robertson founded the company in 1854. The company closed its railway operations in the early 1960s. It retained its stock market listing until 1976, when it was bought and absorbed by National Chemical Industries of Saudi Arabia.
The Tasmanian Government Railways K class was a class of 0-4-0+0-4-0 Garratt locomotives operated by the Tasmanian Government Railways from 1909 – the first Garratt locomotives built.
A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat exchanger, into the boiler water tanks. Installations vary depending on the purpose, design and the type of locomotive to which it is fitted. It differs from the usual closed cycle condensing steam engine, in that the function of the condenser is primarily either to recover water, or to avoid excessive emissions to the atmosphere, rather than maintaining a vacuum to improve both efficiency and power.
The Metropolitan Railway A Class and B Class were 4-4-0T condensing steam locomotives built for the Metropolitan Railway by Beyer Peacock, first used in 1864. A total of 40 A Class and 26 of the slightly different B Class were delivered by 1885. Used underground, the locomotives condensed their steam, and coke or smokeless coal was burnt to reduce the smoke.
Under the Whyte notation for the classification of steam locomotives, 2-6-0+0-6-2 represents the wheel arrangement of an articulated locomotive with two separate swivelling engine units, arranged back to back with the boiler and cab suspended between them. Each engine unit has two leading wheels in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels.
A tram engine is a steam locomotive specially built, or modified, to run on a street, or roadside, tramway track.
The Silverton Tramway was a 58-kilometre-long 1,067 mm railway line running from Cockburn on the South Australian state border to Broken Hill in New South Wales. Operating between 1888 and 1970, it served the mines in Broken Hill, and formed the link between the 1,435 mmstandard gauge New South Wales Government Railways and the narrow gauge South Australian Railways lines. It was owned and operated by the Silverton Tramway Company (STC).
The New South Wales Z12 class was a class of 4-4-0 steam locomotives operated by the New South Wales Government Railways of Australia.
The New South Wales AD60 class were Beyer-Garratt patent articulated four-cylinder, simple, non-condensing, coal-fired superheated, 4-8-4+4-8-4 heavy goods steam locomotives built by Beyer, Peacock & Company for the New South Wales Government Railways in Australia.
The WAGR W class is a class of 4-8-2 steam locomotives operated by the Western Australian Government Railways (WAGR) between 1951 and 1972.
The South African Railways Class A 4-8-2T of 1888 is a steam locomotive class from the pre-Union era in the Colony of Natal.
The South Australian Railways Y class was a class of narrow gauge steam locomotives operated by the South Australian Railways.
The South African Railways Class C1 4-6-2T of 1901 was a steam locomotive from the pre-Union era in the Natal Colony.
The WAGR G class is a class of steam locomotives operated by the Western Australian Government Railways (WAGR) from 1889. The class's wheel arrangement varied; 48 were 2-6-0s and 24 were 4-6-0s.
Sulphide Street railway station was the terminus of the Silverton Tramway in New South Wales, Australia. It served the city of Broken Hill.
The Silverton Tramway A class was a class of 4-6-0 steam locomotives operated by the Silverton Tramway Company.
The Silverton Tramway W class was a class of 4-8-2 steam locomotives operated by the Silverton Tramway Company.
The Tasmanian Government Railways C class is a class of 2-6-0 steam locomotives operated by the Tasmanian Government Railways.
The Walvis Bay 2-4-2T Hope of 1899 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.
